The present invention relates to a flexible pressure sensor using an amorphous metal and a flexible bimodal sensor for simultaneously sensing the pressure and temperature. The sensors according to embodiments of the present invention have stretchable characteristics to be used as an electron skin use by configuring a conductive layer of an amorphous metal. Therefore, the sensors can firmly maintain the conductivity regardless of various physical external forces, or can sense the pressure or simultaneously sense the pressure and temperature. Furthermore, the flexible bimodal sensor according to an embodiment of the present invention is a novel electron skin device capable of simultaneously sensing the pressure and temperature using an amorphous metal. 본 발명은 비정질 금속을 이용한 유연한 압력 센서, 그리고 압력 및 온도를 동시에 감지하는 유연한 이중모드 센서에 관한 것이다. 본 발명의 실시 예들에 따른 센서들은 비정질 금속으로 전도층을 구성하여 전자 피부용도로 사용할 수 있도록 스트레처블(stretchable)한 특성을 가진다. 그래서, 상기 센서들은 다양한 물리적인 외력에도 전도성을 견고하게 유지하고 압력을 감지하거나 압력 및 온도를 동시에 감지할 수 있다. 게다가, 본 발명의 실시 예에 따른 유연한 이중모드 센서는 비정질 금속을 이용하여 압력 및 온도를 동시에 감지할 수 새로운 전자 피부용 소자이다.
